Description

technical field

[0001] The present invention relates to carbon fibers having a small single-fiber elastic modulus distribution, a carbon fiber production method capable of producing the carbon fibers with high operability, and an oil agent for carbon fiber precursor fibers used in the production method. Background technique

[0002] Compared with other fibers, carbon fiber has higher specific strength and specific elastic modulus. Therefore, as a reinforcing fiber for composite materials, it is not only used in sports, aviation and space, but also in automobiles, civil engineering, construction, pressure vessels, Widely used in general industrial applications such as windmill blades. Especially in sports and aerospace applications, there is an increasing demand for higher strength and higher elastic modulus of carbon fibers. Furthermore, while the above-mentioned high performance is required, it is also required to improve the material allowable value by improving the relia...
